application and. tune i, 1911. Serial in. camera To all whom ermay cancer-m Be it known that we, Parnell. Noornirr arid Joni: NooNAN, citizens of the United States, residing at Noonan, in the county of Divide, State of North Dakota, have invented a new and useful Disk-Harrow Atof the sub-soil packer.

A further object of the invention is to provide, as an article of manufacture, a segmental member, adapted' to 4 he dupli cated, to form a sub-soil packer, which may be assembled with the periphery of a harrow disk. v

In the accompanying drawings,-Figure 1 shows in perspective, one of the segmental sections which go to make up the sub-soil packer; Fig. 2 is a side elevation of a harrow. disk, with the per phery of which, the sub-soil packer of our invention is assembled; Fig. 3 is a section on the line '33 of Fig. 2; Fig. 4 is a section on the line 4-4: of Fig. 2.

The sub-soil packer herein disclosed, con

sists of two or more sections, each ot'which is fashioned in accordance with the sho'w-. ing of Fig. 1. The segmental sections which go to make up the sub-soil packer, are identical: in construction, there being-no rights and lefts in the device, each of these segmental sections being denoted generally by the numeral 1. In the intrados otthe segmental section 1, there is a groove 2,

' adapted to fit over the periphery of the barrow disk 3. The section 1, atits periphery, is beveled, as shown at 41.. At one end, the section 1 is fashioned with a tongue 5, in which there is an opening 6, ordinarilycircular in contour, although not necessarily so. At its opposite end, the section. 1 is formed with spaced arms 7. These arms 7 v a are adapted to receive between them, the tongue 5 of a similar section. in the arms 7 there are elongated openings 8,- extended longitudinally of the section In practical operation, a pair or sections 1 are placed about the periphery of the har row disk 3, the tongue 5.11pon one member,

registering between the arms 7 of the adjoining member, the openings 6 alining with the openings 8. Through the alined opens ings, a securing deviceis inserted, the se-' curing devicepreferably, although not necessarily, consisting of. a bolt 9, provided with a nut 10.

From the foregoing it will bei'seen that an. ordinary disk-harrow may be converted readily, into a sub-soil packer, by attaching to the disks of the harrow, the segmental sections herein disclosed. The nut and bolt structures 910 serve to unite the sections 1 with the barrow-disk 3, the periphery of which is received within the groove 2, the

elongated openings 8 permitting an adjustment between the sections 1. I

lt'is to be noted that the sectionsl are identical in construction. Therefore, there are no rights or lettsin the device, and but one form of packer section need be manufactured and carried in stock. g

Having thus described theinventionwhat is claimed is As an article of manufacture, a member formed in the segment of a circle, and having an internal groove, adapted to receive the periphery. of aharrow disk, said seg mental member being formed at one end with a tdngue, and at the other end with; spaced arms, adapted to receive the tongue of a like-member; there being elongated openiuugs in the arms, and an opening in the tongue, of less eX-tent'than' the openings in the arms.

as our own, Wehave hereto afixed our signatures in the presenceot two witnesses.
